  By applying shape memory processing to fabric or thread made of animal hair, it is possible to manufacture products that retain various three-dimensional shapes without the need for advanced sewing techniques, or to produce products that are less likely to lose shape. Can be provided. In order to compete with low-priced products, it is necessary to be able to apply shape memory processing to animal hair materials in a simple and short time and at low cost.

  An object of the present invention is to provide a processing method capable of performing shape memory processing on an animal hair material in a simple manner, in a short time and at a low cost, and a fabric and a thread manufactured by the processing method. And

  The present invention provides a fabric comb or yarn characterized by using animal hair introduced with irreversible cross-linking by cleaving a cystine bond having two sulfur bonds (-SS-) and re-crosslinking formation. provide.

  Further, in the above-mentioned fabric, there is a round shape (there are expressions such as a curl shape, a spring shape, a spiral shape, etc., which will be described in the following unified description), and a fabric subjected to shape memory processing such as a pleat shape. Alternatively, a fabric that is subjected to memory processing in an arbitrary shape such as a yarn, a wrinkle shape, a drawn shape, or a planar shape is provided.

  Further, the present invention provides a fabric or yarn made of animal hair having a cystine bridge having two cystine bridges bonded thereto, immersed in a weakly alkaline hot water to which hot water or an alkali salt is added in a water vapor atmosphere. An irreversible cross-linking introduction treatment by a re-crosslinking formation reaction and then a drying treatment for drying the fabric or yarn subjected to the irreversible cross-linking introduction treatment by the re-crosslinking formation reaction. Provided is a method for processing a fabric or yarn made of animal hair.

  Further, animal hair characterized by cleaving a disulfide bridge having cystine into dehydroalanine and cysteine, and performing a recrosslinking reaction to lanthionine or a recrosslinking formation reaction to lysinoalanine by reaction of dehydroalanine with lysine A method of processing a fabric or yarn or a men's clothing interlining, made of

  In addition, the above-described fabric or yarn is fixed in an arbitrary shape such as a round shape, and is immersed in a weak alkaline hot water to which hot water or an alkali salt is added in a steam atmosphere, and then held for a predetermined time, and then a drying treatment is performed. A method for processing a fabric or yarn made of animal hair, or a men's clothing interlining, characterized by performing shape memory processing.

  In addition, after dipping in water, it is immersed in hot water or weak alkaline hot water to which an alkali salt is added in the water vapor atmosphere and held for a predetermined time, or a fabric or thread made of animal hair, or men's clothing A method for processing an interlining is provided.

  The fabric or yarn of the present invention comprises animal hair having the property that a cystine bond in which two sulfur atoms present in the composition are bonded (-SS-) becomes an irreversible cross-linking bond by cleavage and generation of a re-cross-linking bond. It is used as a raw material, and in its processing, it is immersed in hot alkaline water with hot water or alkali salt in a steam atmosphere, and irreversible cross-linking introduction treatment is performed by cleavage of cystine cross-linking and re-cross-linking formation reaction. As a result, shape memory processing can be applied to animal hair material reliably and easily in a short time and at low cost.

  Animal hair typified by wool is composed of a protein called keratin and is characterized by having a (-SS-) cross-linked structure in which two sulfur atoms are bonded. Keratin is tightly bound by sulfur atoms to form a three-dimensional network so that the chains of macromolecules called peptides do not fall apart, and the entire tissue is tough and elastic. . As shown in the figure, this bond is mainly composed of cystine bridges called disulfide bonds.

  In order to give a predetermined deformation to such a strong and stable structure and stabilize it in its shape, it is necessary to cut this bond and reconnect it at a place where it becomes more stable for the structure after deformation. In this case, reversible oxidation-reduction reaction is often performed by treating with a reducing agent such as thioglycolic acid, cutting the disulfide bond once, and regenerating the disulfide bond when the structure stabilizes after deformation. . FIG. 2 shows the reaction mechanism when thioglycolic acid is used. Permanent treatment of hair and pleating of skirts are examples of applications of this reaction.

  In the examples of the present invention, cross-linking is performed by applying a reaction different from the above reaction mechanism.

  This is because disulfide bonds (-SS-), which are present in large amounts in the animal hair protein shown in Fig. 1, are converted into new bonds when treated with hot water or weak alkaline water, and lanthionine and lysinoalanine bonds are converted. It utilizes the property that stable crosslinks are formed between protein molecules by the production of crosslinkable amino acids.

  FIG. 3 shows a reaction formula of the breaking of the crosslink and the formation of recrosslink.

  One sulfur atom (S) is removed from cystine to produce dehydroalanine and cysteine, and the reaction system in which dehydroalanine and cysteine are produced to produce lanthionine, and the resulting dehydroalanine is a nearby lysine (a constituent amino acid of animal hair). 1), and lysinoalanine is produced, and both are irreversible reactions. Therefore, the produced lanthionine and lysinoalanine bridge are stable.

  As described above, the processing method of the yarn or fabric made of animal hair of this example or the interlining of men's clothing is made of a fabric or yarn made of animal hair having cystine bridges in which two sulfur atoms are combined, In a steam atmosphere, immerse in hot water or weakly alkaline hot water added with an alkali salt to perform irreversible cross-linking introduction treatment by cleavage of the cystine bridge and re-crosslinking formation reaction, and then irreversible by the re-crosslinking formation reaction. It is characterized by comprising performing a drying treatment for drying the fabric or yarn subjected to the mechanical cross-linking introduction treatment.

  Furthermore, this processing method is characterized in that cystine having a disulfide bridge is cleaved into dehydroalanine and cysteine, and a recrosslinking formation reaction is performed on lanthionine, or a recrosslinking generation reaction is performed on lysinoalanine by reaction with lysine. .

  Furthermore, an arbitrary shape such as a round shape is fixed to the above-mentioned fabric or yarn or interlining, and is immersed in a weak alkaline hot water to which hot water or an alkali salt is added in a steam atmosphere, and is then held for a predetermined time, and then dried. It is characterized by performing shape memory processing by performing processing.

  Further, this processing method is characterized in that after the animal hair material is immersed in water, it is immersed in weak alkaline hot water to which hot water or an alkali salt is added in the water vapor atmosphere, and is maintained for a predetermined time. .

  And, by this processing method, the fabric comb is characterized by using animal hair that has been irreversibly cross-linked by generating a re-cross-linked bond by cleaving a cystine bond having two sulfur bonds (-SS-). Yarn or interlining is supplied, and cloth or yarn or interlining that has been memorized into an arbitrary shape such as a round shape is supplied.

  Using this re-crosslinking formation reaction, cloths, yarns, nonwoven fabrics, etc. made of animal hair material previously placed in a certain deformation state or containing animal hair material are heated in hot water or weakly alkaline hot water. Can be fixed in a desired shape.

  Unlike the reaction by reduction and oxidation described above, this reaction does not require a chemical such as a reducing agent or an oxidizing agent, and proceeds easily only by hot water or by adding an alkali salt of a catalyst level to water. Since the generated cross-linked bond is stable, the processing can be completed by a simple process of drying after the treatment.

  Examples will be described below.

  Wrap the bottom of the core of the animal hair (the base fabric of the interlining) with a rod of about 1 cm in diameter (change the size of φ according to the desired radius) in the lateral direction of the interlining, and finish the winding Secure it firmly by sewing it with a thread.

  Next, the wound part (part which wants to have a round shape) was immersed in the boiling 0.01% aqueous solution of sodium carbonate, and treated at the boiling point for 50 minutes.

  The treatment time and the type and concentration of the salt to be added depend on the composition of the core base yarn (mixing ratio of animal hair) and thickness, weaving density and amount of glue, and the type of outer material and lining. Since the appropriate radius and hardness as the interlining are different, conditions other than the above may be used.

  Subsequently, after rinsing with water, the water was lightly drained and dried in a drying chamber at a temperature of about 70 ° C. to 100 ° C. for 30 minutes to completely drain the water.

  The drying temperature is an important factor from the standpoint of processing that continues from treatment with high-temperature water, not just drying. It depends on the type of interlining and the type of outer material, and the required size of the warp and interlining are required. Set according to the bending hardness.

  After drying, remove the core rod and lightly iron it to finish the shape.

  A white cloth (wool) wool 100% for JIS dyeing fastness test was adopted as a sample. The sample was collected in a size of 5 × 5 cm, and the periphery was sewn with a sewing machine, leaving a margin of about 5 mm, to obtain a test piece. Further, while keeping this test piece as horizontal as possible in the weft direction, the test piece was wound from the end so as to have an inner diameter of about 10 mmφ, and the end of winding was sewn and stopped to prepare a cylindrical sample. This cylindrical sample was immersed in 50 times the amount of distilled water, treated for 4 hours at the boiling point, taken out, dried lightly so as not to break the shape, and dried at 80 ° C. for 30 minutes. The thread which had been sewn from the dried cylindrical sample was removed to complete the processing.

  The round shape was memorized into the test piece by the processing, and the shape that was wound in the round shape from both ends was fixed.

  When the iron is applied, it becomes a flat test piece, but when it is left for a while or when steam is blown, it becomes a round shape again.

  A white cloth (wool) wool 100% for JIS dyeing fastness test was adopted as a sample. The said sample was extract | collected to the magnitude | size of about 10x10 cm, and it was set as the test piece.

  The test pieces were put together so as to be grasped with the palm of the hand, and the shape was fixed with rubber bands. Next, it was immersed in 50 times the amount of distilled water, treated for 1 hour at the boiling point, taken out, wiped lightly with a filter paper, and then dried at 80 ° C. for 30 minutes. The dry rubber band was removed to complete the processing.

  Random wrinkles that were created when the test pieces were put together into small shapes were memorized as they were and wrinkled.

  A white cloth (wool) wool 100% for JIS dyeing fastness test was adopted as a sample. The said sample was extract | collected to the magnitude | size of about 10x10 cm, and it was set as the test piece.

  The center part of the test piece was sewn into a circle having a diameter of about 3.5 cm with a thread, and the end of the sewing was pulled to form a squeeze shape. Next, it was immersed in 50 times the amount of distilled water, treated for 1 hour at the boiling point, taken out, wiped lightly with a filter paper, and then dried at 80 ° C. for 30 minutes. After drying, the thread sewn was removed, and the processing was completed.

  The shape of the diaphragm was fixed as it was on the test piece, and a three-dimensional diaphragm pattern was memorized.

  50cm sample yarn of 100% wool was immersed in a 0.01% sodium carbonate aqueous solution at 60 ° C for about 3 minutes, confirmed to be completely wet, wrapped around a bamboo basket with a thickness of about 2mmφ, The winding start and end were fixed with rubber bands. Next, it was placed in a steamer with steam and processed for 1 hour. After the treatment, it was simply washed with water, excess water was removed with a filter paper, and then dried at 80 ° C. for 30 minutes. The dry rubber band was removed to complete the processing.

  The shape memory thread that memorized the spring shape and expanded and contracted was made.

  Four sample yarns of 100% animal hair were bundled and tied together in a length of 20 cm, and the four bundles were simultaneously wound around a glass rod having a thickness of about 10 mmφ, and the beginning and end of winding were tied to the glass rod and fixed. . This was immersed in water, treated at the boiling point for 50 minutes, then pulled up, easily shaken off the water, and dried at 80 ° C. for 30 minutes. A glass rod was taken from the dried test yarn to complete the processing.

  The R shape was memorized in each of the four test yarns.

  Animal hair is contained in fabrics made of animal hair, knitted fabrics, non-woven fabrics, etc., or yarns in the direction in which they are rounded (warp direction or weft direction) (the mixing ratio of animal hair is preferably 30% or more) The method of attaching the knitted fabric or the nonwoven fabric to the fabric including the woven fabric made of the material or animal hair (the mixing rate of the animal hair is preferably 30% or more) is as follows.

  Wind the sample cloth in the direction you want to apply the curve. In this case, in order to prevent the loss of shape in the subsequent processing, a rod-like object is taken up from the end, and the end of winding is firmly fixed by a method such as sewing with a thread. The rounding at the time of normal winding needs to be smaller than the rounding at the finish. The smaller the rounding at the time of winding, the smaller the rounding at the finish and the higher the effect of shape memory processing.

  Next, all of the sample wound up into a cylindrical shape or only the portion to be rounded is put into hot water (approximately 70 ° C. to the boiling point), and in an appropriate time of approximately 10 minutes to 6 hours. To process. In this case, the longer the processing time, the closer to the size of the radius at the time of winding. In addition, the processing time can be shortened as the processing temperature increases.

  The treated sample is dried at a temperature of room temperature to about 110 ° C. Whether it is dried naturally or using a warm air dryer, completely remove moisture. Also, if the shape can be kept clean, it is possible to dry burn after removing the core rod in advance.

  After drying, the core rod is removed and the process is terminated.

  The finished round shape depends on the processing temperature, processing time, drying temperature, and sample condition (thickness, size, hardness, type, type and proportion of animal hair contained in the material, thickness of the constituent yarn, etc.), etc. Change. It can be loose and can have several curls.

  In the case where the sample is a woven fabric or a knitted fabric, it is better to avoid the movement of the constituent yarns such as necking in order to keep the finished shape after the treatment. Therefore, if possible, it is desirable to sew the periphery of the specimen before processing, or to sew and prevent the thread from moving.

  About the sample similar to Example 7, a cloth is wound up and fixed by the same method.

  Next, the whole sample wound up into a cylindrical shape or the portion to be rounded is sufficiently wetted by immersing it in water. At this time, there is no problem even if the temperature of the water is raised to near the boiling point in order to make the sample easy to wet. When the sample is sufficiently wet with water, the sample is taken out, and steaming is performed for 10 minutes or more using an apparatus capable of obtaining a sufficient amount of steam and a temperature of about 70 ° C. or higher, such as a steaming box.

  After the steam process, the processes after the drying process are performed in the same manner as in Example 7 to complete the processing.

Also, if the shape can be kept clean, it may be dried after removing the material used to maintain the shape such as the core rod and clip.

  After drying, the material used for fixing the shape is removed from the sample, and the process ends.

  The finished shape varies depending on the processing temperature, processing time, drying temperature, and the condition of the sample (thickness, number of twists, hardness, composition, etc.). In addition, the finished shape after processing may not be maintained due to a phenomenon such as unwinding of the yarn.

Wet it sufficiently by immersing it in water prepared in a 01% aqueous solution. At this time, there is no problem even if the temperature of the aqueous solution is raised to near the boiling point in order to make the sample easy to wet.
